Ivory stepped in front of a Montana State receiver and raced 41 yards untouched into the endzone with 6:14 to play in the second quarter, giving Cal Poly (3-0) the lead for good at 14-7.

Senior place kicker Byungwoo Yoon added two field goals in the second half spanning 19 and 28 yards for a 20-14 Cal Poly lead and Martinez capped a 75-yard, nine-play drive with his clinching nine-yard run with 2:00 remaining on the clock.

It was Cal Poly's sixth straight win over Montana State and the Mustangs are off to a 3-0 start for the second consecutive season. The Mustangs finished 7-4 a year ago.

Martinez finished with 87 yards on 14 rushed while sophomore Jeremy Konaris added 68 yards on nine trips as Cal Poly amassed 217 yards on the ground.

Junior quarterback John Mende, on his 21st birthday, took over for Cordel Webb late in the first half and completed eight of 13 passes for 107 yards.

Webb accounted for Cal Poly's first touchdown -- a 26-yard pass to Darrell Jones with 5:38 to play in the first quarter.

Jones finished with eight catches -- a career-high -- for 123 yards. The senior wide receiver had caught seven passes in a game five times.

Mustang punter Tim Chicoine averaged 46.2 yards on four punts with no Bobcat returns.

Cal Poly had the edge in total offense, 367 to 248, and in first downs, 20 to 18.

Montana State junior quarterback Travis Lulay completed 17 of 38 passes for 162 yards, but was intercepted twice.

Ivory and Mustang senior linebacker Jordan Beck each collected their third interceptions of the season. Ivory also had three pass breakups while Beck led the Mustangs with 11 tackles, including three for lost yardage and a pair of pass deflections.

Cal Poly, which has won seven of its last eight games, has a bye next week and will play its second home game in two weeks, hosting South Dakota State at 6 p.m. in Mustang Stadium. It will be Cal Poly's inaugural Great West Football Conference game and Hall of Fame Weekend.
